There are a few easy ways you can tell huckleberries and blueberries apart. Huckleberry leaves have resin dots on the underside much like bayberry leaves. You can often see them with your naked eye, especially on a sunny day. You can also rub the leaf on a piece of white paper and a yellow stain will result. Highbush and lowbush blueberry both lack these glands. With the berries, you can slice them in half with a pocketknife or your fingernail (if you imagine the berry as the earth, the stem would be the north pole and you would slice it through the equator). In the case of a huckleberry you will see ten large seeds arranged in a circle. This is evident even before the berries mature. These seeds result in a somewhat crunchy berry that has never been commercially desireable. Blueberries have more seeds which are much smaller and randomly arranged.
It's also interesting that although blueberries and huckleberries resemble each other, blueberries are more closely related to cranberries than they are to huckleberries.
